| Abstract(in English) | The purpose of this study is the application to nanocrystal memory noticed as a non-volatility memory of next generation. We made germanium(Ge) nanocrystals self-assembled in silicon dioxide(SiO_2)film by metalorganic decomposition(MOD)method, and investigated their crystallinities and electrical characteristics. When Ge is diffused and heat-treated, it self-assembles in SiO_2 finally changes to nano-size crystals. The size of Ge nanocrystal obtained in this study was estimated in the range of 3 to 5nm from the result of Raman spectroscopy measurement. Blue light emission from the growth of Ge nanocrystals was observed at room temperature from the result of photoluminescence(PL)measurement. Moreover, the flat-band voltage of C-V characteristics certainly changed by the electron-injection to SiO_2/Ge/SiO_2 quantum well. |
